Which reminds me... Alex.. you never answerd my question... Can the SB's support taking a 48volt DC input?     -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Shawn Mitchell Sent: Saturday, July 05, 2003 22:25 To: [EMAIL PROTECTED] Subject: RE: [smartBridges] Now have 45 customers on 1 aPPo Anyone that makes UPS's for datacenters... Triplite.. APC.. Lorain (Their Vortex series)... Lambert.... and about a dozen more...   A lot of datacenter equipment is 48v DC powerd...     -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Westman, Michael (324) Sent: Saturday, July 05, 2003 21:41 To: [EMAIL PROTECTED] Subject: RE: [smartBridges] Now have 45 customers on 1 aPPo Who makes the 48v UPSes? -----Original Message----- From: Shawn Mitchell [mailto:[EMAIL PROTECTED] Sent: Saturday, July 05, 2003 8:35 PM To: [EMAIL PROTECTED] Subject: RE: [smartBridges] Now have 45 customers on 1 aPPo Even cheaper... 12volt car batt, 12 volt charger with a trickle charge capability.... :D   But they do make UPS's that spit out 48v DC with a normal utility input...   According to the PoE spec's, equipment is suppose to be able to take 12-48volts...  But SB would have to comment on if they accually followed the spec's/RFC's....  :D -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Tom Haynes Sent: Saturday, July 05, 2003 18:30 To: [EMAIL PROTECTED] Subject: RE: [smartBridges] Now have 45 customers on 1 aPPo You can make one easy enough. Around $130-180. Look at altronix.com for the 18-24vdc regulator/back/charger module ($45-75) get two 12v 7 amphour ($12 ea) or larger gel-cell or sealed lead-acid batteries and a 1200VA transformer ($60-80) and you are all set. This will charge the batteries and regulate the voltage when AC is normal, back up to batteries when AC fails and should run for 12-14 hours on batteries if you use the 7Ah ones. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Westman, Michael (324) Sent: Saturday, July 05, 2003 6:03 PM To: [EMAIL PROTECTED] Subject: RE: [smartBridges] Now have 45 customers on 1 aPPo I just want a 1400 UPS from APC that spits out DC.  That way we don't have to power the invertor. -----Original Message----- From: Shawn Mitchell [mailto:[EMAIL PROTECTED] Sent: Saturday, July 05, 2003 5:58 PM To: [EMAIL PROTECTED] Subject: RE: [smartBridges] Now have 45 customers on 1 aPPo These power condition as well...  Their not the cheaper UPS's you goto Best Buy and pay $100 bucks for.  I have software that I can look at the power level's from the utility, and from the UPS plugs and see the diff.   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Tom Haynes Sent: Saturday, July 05, 2003 17:00 To: [EMAIL PROTECTED] Subject: RE: [smartBridges] Now have 45 customers on 1 aPPo This does not pertain to your problem. Haveing an average UPS does not eliminate spikes, surges and some sags. Only ones labled as power conditioning UPSs do that (and the cheaper one don't do it that well). When the average UPS is not on battery backup it acts just like a surge supressor and must be rated to handle the level of noise on your power lines. Just an FYI   TO SMARTBRIDGES - Has any testing been done to see how a non-sine wave AC source affects the units? Most UPS produce a modified square wave or sawtooth AC wave and not a pure sine wave. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Shawn Mitchell Sent: Saturday, July 05, 2003 4:06 PM To: [EMAIL PROTECTED] Subject: RE: [smartBridges] Now have 45 customers on 1 aPPo Kinda sounds like something I came across a few weeks ago....   Here on my desk, I have a aPP.  It's always up and running, plugged into a UPS and a network that has everything on a UPS. (so no surges anyplace)  Anyway, I upgraded the firmware several several weeks back. (forget when exactly).  I got home, plugged in my laptop, slamed in my wireless card... and went no where.  I associated just fine, but I couldn't pass any packets.   I got into simpleMonitor and looked at the ethernet stats, and it shows packets being sent and recived.  I reboot the AP... reassociate... and it passes 3 packets, then dies...  I went aroun and around with it with reset's, fact resets, fw reloads... etc etc... for about 2 hours.    And after messing with it that long, I finally got it to work again.  Kinda screwy if you ask me... something that's been sitting here working for that long then all of a sudden does that... -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Mark P. Sullivan Sent: Saturday, July 05, 2003 9:49 To: [EMAIL PROTECTED] Subject: [smartBridges] Now have 45 customers on 1 aPPo Well�thought I would keep everyone posted on my numbers. As of last weekend, we went from 30 to 45 units off a single aPPo.  I actually have 30 units directly off my head-end aPPo (one of which is the repeater) and 15 more off the repeater.  The latest 15 are all airBridges.  We are pulling about 1.2 Gig per day through the head-end (500 meg of which is from the repeater clients). 1.      I did the bulk update with the latest simpleNMS and changed RTS/CTS and FRAG to 1496 and 100 on all client units (not head-end).  This was a pretty cool feature.  However, twice within 1 day ALLLL my units lost association and I had to reboot my head-end aPPo to get them back.  So�needless to say, I changed the RTS/FRAG settings back to default.  No problems since. 2.      I used simpleDeploy to burn ALL new customers.  I then hot tested them for a minimum of 24 hours prior to deployment with none of them blinking an eye.  Out of the 15 deployed, I have 3 units that are losing association and not getting it back.  I have had the customer do a power reset by pulling the plug, factory default reset, etc, etc�.but no luck.  Oddly enough, one of the 3 units just came back online this morning with no assistance.   Pretty darn flakey!  Note: all the units could be pinged from the wired side and logged into (but DEAD on the wireless side).  Now I am going to go do some climbing and replacing. Side Note: My head-end aPPo which has been online since Dec 25th 2003 is going down hill quick.  The symptoms are this: 1.      About 3-4 times a week, the unit becomes unresponsive on the Ethernet side while still passing traffic (hard reboot). 2.      The RTS/FRAG thing mentioned above really had me shaking in my boots (reset to default). 3.      I have been working with sB for a while on this flakey aPPo, and I am now struggling with EC to get a replacement unit before this one dies. I think that sB is awesome.  They are VERY responsive and have even phoned me personally to resolve issues.  All my units previously deployed are working wonderfully.  3 out of the latest 15 have not.  That doesn�t look good, but I am sure they are getting to the bottom of it.  Maybe it is a bad simpleDeploy release??
